Two masses of weight 30.0 NN are suspended at opposite ends of a rope that passes over a light, frictionless pulley. The pulley is attached to a chain that goes to the ceiling. What is the tension in the rope? What is the tension in the chain?

4. A 52 kilogram girl is rappelling down a vertical cliff face as shown. With her feet planted on the wall, her legs form a 15° angle of elevation. The rope forms a 31° angle with the wall. A) What force must she exert on the wall with her legs? B) What is the tension in the rope supporting her weight? 5. A 5 kilogram lamp is hung from a horizontal arm attached to a vertical post, and the horizontal arm is supported by a steel cable attached as shown. If angle 0 = 30°, A) what is the force exerted by the horizontal arm on the vertical post? B) How much tension is in the steel support cable? 6. A 125-pound female circus acrobat is suspended from a rope in mid-air as shown. How much force will her partner have to apply to his end of the rope to avoid being pulled off his platform? = 3/5 g=mg

A rope is attached to two posts and supports a 145 kg sign. What are the tension in each rope if the ropes form a 35 degree angles?

A window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 192 N and is 3.1 m long. What is the tension in each rope when the 710–N worker stands 1.06 m from one end? Smaller tension? Larger tension?
